Short wave UV (UVC 254nm) has a pronounced bactericidal action. UVA (c.320nm) has a limited effect. I saw somewhere an article where endoscope/fiberoptic applied white light had a marked kill effect on the bug 'heliobacter' which causes gut ulcers. On the Net I came across a one-line reference to 'Super White Light' as an emerging bactericide technology, so who knows- does the 'Ozone-lite' work, or is it an advertiser's ploy to shift low energy bulbs at a premium price? Me? I open the windows for some good old-fashioned ventilation, it's cheaper.
